[PATCH] iommu/arm-smmu-v3-iommufd: Separate vDEVICE allocation list

[Bagas Sanjaya]

Stephen Rothwell reports htmldocs warnings when merging iommufd tree:

Documentation/userspace-api/iommufd:335: include/uapi/linux/iommufd.h:456: ERROR: Unexpected indentation. [docutils]
Documentation/userspace-api/iommufd:335: include/uapi/linux/iommufd.h:457: WARNING: Block quote ends without a blank line; unexpected unindent. [docutils]

Fix them by separating vDEVICE allocation list from preceding paragraph.

Thanks for the fix.

I was about to send a v3 over a fix :)
